Ghost is a Vintage knife in MM2, originally obtainable in Murder Mystery 1 from the MM Shop and transferable to MM2 once the game’s sequel was released and the game was renamed to Murder Mystery 2. Ghost used to give you the ability to throw knives faster. At the moment Ghost is only available through trading.
The Ghost knife’s spearhead-shaped blade is tealish-white in color. This knife does not have a guard. Instead, it has a blackish-grey tape around the bottom that acts as its handle. It resembles a dagger with a blue blade and a dark handle. Ghost is the smallest and shortest knife in the game.
